TRX W-Fly

How to do it

Hold the TRX handles overhead and lean back at a steady angle, feet planted shoulder-width apart in a straight line from head to heels.
Brace the core to lock the plank position before initiating the pull.
Pull the handles in toward the ribs while driving the elbows down and back until the arms form a W shape, bringing the shoulder blades together.
Keep the elbows close to the body during the pull rather than flaring them wide like the T-fly.
Exhale through the W pull, then inhale as you extend the arms back to the overhead starting position with control.
Avoid shrugging the shoulders toward the ears at the top, which takes tension off the upper back.
